FIELD: communication technique.
SUBSTANCE: invention relates to terminal positioning means. First terminal sends a capability request message to a second terminal. Opportunity request message is configured to request at least one of information on possibility of using time difference of arrival on sidelink-downlink (SL-DL TDOA), information on possibility of using angle of arrival on sidelink (SL-AOA), information on possibility of using round-trip time on sidelink (SL-RTT) or information on the possibility of using the difference in the time difference on the sidelink-downlink (SL-UL TDOA). Second terminal sends an opportunity message to the first terminal. Opportunity grant message comprises at least one of information on possibility of using SL-DL TDOA for sidelink band, information on possibility of using SL-AOA for sidelink band, information on possibility of using SL-RTT for sidelink band or information on possibility of using SL-UL TDOA for sidelink band.
EFFECT: provision of terminals positioning on the basis of LTE positioning protocol in sidelink.
